about CSS selectors

I recently came across a post of Jack Slocum about CSS Selectors implemented in diffrent js frameworks and sience I am a YUI user and they recently launched their own library for this here is a similar comparative test: http://florin.supermedia.ro/slickspeed/, the list of selectors is not the same as the one used by Jack, i actualy used the default list.

I expected YUI to give poor results because the component is still in beta stage but what surprised me was how fast was ExtJS. It was way faster then the veterans of js frameworks JQuery and Prototype on all browsers i tested (Firefox 2 , IE 6 , Opera 9.25, Safari 3 beta). Unfortunetly MooTools gives alot of errors (XPath Exceptions) so the test is not really relevant for this particular framework.

I use YUI in my developing work but not because i think it’s the best. I like how the code is structured and all the concepts behind it, I actualy learned more JS by using YUI and watching Douglas Crocford video materials.

The test code can be found here http://code.google.com/p/slickspeed/.

Also here are the websites where u can find the frameworks i’ve tested: http://developer.yahoo.com/yui/, http://extjs.com/, http://jquery.com/, http://www.prototypejs.org/, http://mootools.net/

I had in mind to make a similar test for the Drag and Drop component, but curently i lack the free time to do it :) . From what i’ve tested for stiri24.ro YUI was faster then JQuery.
